ALRIGHT. SO NOW YOU KNOW. NO MORE PUTTING VOCALOIDS IN UTAULOIDS FOLDER C:
Also, just in case anyone thinks I'm being a smart ass, I'm not trying to, I'm just trying to help out. But if you still think just because I added all that info, it's not like I knew about the updates, I actually was looking a Vocaloid chart to see if I missed any for any season, and I didn't know about the updates, so don't make it seem like I knew this all and I am being a smart ass. Arigatoo Gozaimasu. Konbate Kudasai! Sayoonara!
